By means of DC to DC chopper circuits with transformer isolation. 7.1 MGDs with optocouplers applications where high currents are being switched rapidly. Because of the dv/dt seen by the V EE pin 7.2 Pulse transformers A pulse transformer is, in principle, a simple, reliable and must be overcome with additional components. A transformer can only transfer to the secondary the AC used for duty cycles between 35 and 65%.
